Evaluation of Water Resources in Wadi El Natrun, Western Desert, Egypt

Groundwater of the Pliocene aquifer in Wadi El Natrun area represents the primary source of reliable water for drinking and agriculture uses. This research focuses on the study of the different sources of water in the study area and determines the origin and quality of this waterand also is interested in studying hydrogeochemical processes that affect them and the movement of water through the analysis and determine the activity of different elements, and also to changes in hypothetical salts with the direction of water flow in three sectors of the region and the statement of the most important geochemical processes that occur. Finally it is evaluated the suitability of the water for different purposes. The results show that, there is a zonation of chemical composition; this zonation is characterized by a change of cation species from dominantly Ca and Mg near the east to Na-dominated waters in the west. Mirroring this, anions change from HCO3 type to Cl and SO4 type.The ions displays two grades of metasomatism along flow path, first the stage of mineralization(HCO3>Cl>So4) at the east then the advanced stage of mineralization (Cl>SO4 >HCO3) at the west. According to the(W.H.O.2005), 45 % of tested groundwater samples are permissible for drinking. Most groundwater samples of the Pliocene according to SAR andRSC are suitable for irrigation purposes under normal condition, but all surface water samples (lakes) are saline water,so it is not valid for drinking or irrigation purposes

A finite volume method for scalar conservation laws with stochastic time-space dependent flux function

We propose a new finite volume method for scalar conservation laws with stochastic time–space dependent flux functions. The stochastic effects appear in the flux function and can be interpreted as a random manner to localize the discontinuity in the time–space dependent flux function. The location of the interface between the fluxes can be obtained by solving a system of stochastic differential equations for the velocity fluctuation and displacement variable. In this paper we develop a modified Rusanov method for the reconstruction of numerical fluxes in the finite volume discretization. To solve the system of stochastic differential equations for the interface we apply a second-order Runge–Kutta scheme. Numerical results are presented for stochastic problems in traffic flow and two-phase flow applications. It is found that the proposed finite volume method offers a robust and accurate approach for solving scalar conservation laws with stochastic time–space dependent flux functions

Patient’s Perception of Community Pharmacist in North Malabar region of Kerala, India: A questionnaire based study

Pharmacists as vital healthcare professionals play significant role in effective medication management and their use among the patients. However the perception of community pharmacist  among the public needs to be assessed for effective role and further patient care. This questionnaire based study was aimed to identify the perception of patients towards the community pharmacist in north Malabar region of Kerala, India. The questionnaire consisted of 16 questions with sections evaluating the demographic details (age, sex, marital status, education level & occupation) and the perception of patients towards the community pharmacist. The results were prepared based upon the responses obtained from 110 patients. The study respondents consisted of 51 (46.36%) adults (18-59 years) and 59 (53.63%) geriatrics (above 60 years). Based on their education level, 9 (8.18%), 35 (31.81%) and 66 (60%) participants were illiterate, secondary school and graduate holders respectively. The respondents of the study informed that the pharmacist enquired about their past medication history (58, 52.73%), any allergic reactions (21, 19.1%) and use of any herbal medication (31, 28.18%) prior to the dispensing process. The patients also responded that proper advice regarding dosage (90%), side effects (25%), storage (12%), healthy eating & exercise (10%) were also provided by the concerned pharmacist. As a matter of fact, 91 out of 110 patients thought the pharmacist service were good, 17 thought they were fairly good and 2 were of the opinion that it was poor. The pharmacy rating was evaluated as good by 32 (29.09%), fairly good by 78 (70.90%) and no respondents were of opinion that the pharmacy was poor in its service. Through this study, we found that the overall perception of patients towards the pharmacist in concerned community pharmacy setting was good. To further improvise their role, continued pharmacy education programmes, better communication skills and good professional training must be imparted among the community pharmacists
